SHARE iterates these steps till CERN provided programs for parameter optimization terminates. Several initial input parameters sets can be tried to assure that the same best, stable parameter fit is found. If such a solution was not achieved, it is advisable to evolve a better initial input parameter set from fits that worked nearby either in energy or centrality.
In order to account for the quark flavor chemistry we introduce the following quantities which go back to the initial model of QGP hadronization of 30 years ago [1]}, for illustration see also Fig. REF :
